GAS-GOVERNOR.

Specification of Letters Patent.

Patented Nov. 5, 1907.

Application filed June 4. 1907. Serial No. 377,172.

To all whom it may concern:

Be it known that we, ANDREW Sonnen and WILLIAM H. FrNrRooK, citizens ofthe United States, residing at Chicago, in the county of Oook and Stateof Illinois, have invented certain new and useful Improvements inGas-Governors; and we do hereby declare the following to be a full,clear, and exact description of the invention, srrclr as will enableothers skilled in the art to which it appertains to rrrake and use thesame.

Our invention relates to improvements in automatic gas governors.

It has for its object to provide a simple and comparatively cheap deviceof this nature which will give satisfactory results.

The invention consists in the features of construetion and combinationsof parts hereinafter described and specified in the claims.

In the accompanying drawing illustrating the preferred embodiment of myinvention: Figure l. is a central vertical sectional view of thegovernor. Fig, 2 is a detailed view or' the valve, and Fig. 3 is adetailed view oi the toggle and adjusting screw connected thereto.

Referring more particularly to the drawing, l designates the castingcomprising the body of the governor. Said body has a straight bore toreceive the sliding tubular valve 2. The inlet passage 3 is at rightangles to the valve while the out-let Ll is in line therewith, There isanother tubular offset portion 5 of the body also ar'- ranged at rightangles to the valve but above the inlet passage. To the end of saidoffset 5 is secured the casing 6 containing the diaphragm 7. Said casingis made in two parts fastened together at their edges by bolts S. Theedge of the diaphragm, which is preferably made of German silver, isclamped with packing 9 between the edges of the parts of the casing.Said casing is secured to the offset 5 by screws l0 and the joint ispacked as at ll. The cap l2 below the valve may be taken off to removeany foreign matter which may collect in the body. The valve 2 has slotsI3 cut in its wall opposite the inlet, and the body of the governor isbulged out around said slots to permit the gas to pass arorrnd and enterboth of them. The upper end of said valve is open save for a cross piece14 into which a pin l5 is screwed. Said pin has a horizontal slot I6 inits head whereby it is connected to one end of a lever I7 arranged inthe trrbular offset 5 and pivoted to an extension of the inner part ofthe diaphragm casing. The other end of said lever is bent up andpivotally connected to a link or toggle I8. An adjusting screw I9 isswiveled to the toggle being let into a slot opening on the bottom ofsaid toggle. Said screw passes through a nut 20 in the center of thediaphragm and extends beyond the casing where it may be grasped foroperation. The diaphragm is pressed by a coiled spring 2l partiallynclosed in a hollow screw 22 adjustable in the outer part of the casingand having an opening in 'its end through which the adjusting screw I9extends. Said screw 22 is fitted with a lock nut 23 which is screwedagainst the casing to hold said screw in proper adjust ment.

It will be noted that there are two means of adjusting the valve, namelyby the screw pin l5 and the screw I9. The tension on the diaphragm maybe adjusted by means of the hollow screw 22. In this way very tineadjustments may be made to conform to the number of lights used and thepressure of the gas in the pipes. Experiment has shown that the'use ofour governor reduces the gas bill at least one-third. There is alwaysenough leakage through the valve to act on the diaphragm which keeps thevalve closed when not in use.

We claim z l. A gas governor' of the character described comprisingl abody or casing having inlet. and outlet ports. a valve ar ranged acrosssaid inlet port, an adjusting screw engaging' said valve and having aslot in its head, a diaphragm, and an intermediately pivoted lever'connected at one end to said diaphragm and at the other end to the slotin the head ot' said screw.

A gas governor of the character' described comprising a body or casinghaving inlet and outlet ports, a valve arranged across said inlet port.a diaphragm, a pivoted lever connected :it one end to said valve, atoggle connected te the other end of said lever, and a screw havingswivel connectioxr with said toggle and adjustabl)l engaging thediaphr'agni.

3. A gas governor of the character' described comprising :r body orcasing having inlet and outlet ports, a vulve arranged across said inletport, a diaphragm, a pvoted lever connected at one end to ,said valve,an adjustable screw connected to the other end of said lever and to saiddiaphragm, a coiled tension spring engaging said diaphragm, a hollowscrew engaging the casing and partially inclosing said spring, the iirstmentioned screw extending through said spring and beyond said hollowscrew for operation.

-L A gas governor of' the character described comprising a body or'casing having inlet and orrtlet ports, a valve arranged across saidinlet port, a diaphragm, a pivoted lever' connected at one end to saidvalve, an adjustable screw connected to the other end ot' said lever andto said diaphragm, a coiled tension spring engaging said diaphragm, ahollow screw engaging the casing and partially inclosing through saidspring and beyond said hollow screw for operation and a lock nut on saidhollow screw and adapted to engage the outside ot' the casing.

5. A gas governor of the character described comprising a body or casinghaving inlet and outlet ports, a slotted tubular valve adapted to moveacross said inlet port, a diaphragm and a lever pivoted intermediate ofits ends, one end of said lever being connected to said diaphragm andthe other' end connected to said valve.

In testimony whereof, we aiix our signatures, in presence of twowitnesses.
